Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.

Examples

As shown in figures 1-4, the clamping pliers for mounting a cross buckle for connecting a protective screening on a building comprise a pliers handle 1, a cross joint rotary head 2, a pliers head 3 and a clamping block 4, the clamp handle 1, the jaw joint rotating head 2 and the clamp head 3 are sequentially connected to form a clamp body 5, the jaw joint rotating heads 2 on the two clamp bodies 5 are connected through a rotating shaft 6, the binding clip 3 is a double binding clip with a U-shaped structure, the double binding clip comprises a left binding clip 7 and a right binding clip 8, the clamping surfaces of the left tong head 7 and the right tong head 8 are respectively and correspondingly provided with arc-shaped clamping openings 9, the structure of the double-headed tong is basically the same as that of the double-headed tong special for installing and connecting the existing cross buckle 14, the two ends of the inner side surface of the left binding clip 7 are respectively hinged with a clamping block 4, the two ends of the inner side surface of the right binding clip 8 are also respectively hinged with the clamping blocks 4 corresponding to the left binding clip 7, and the clamping surfaces on the inner sides of the clamping blocks 4 are correspondingly provided with arc-shaped clamping ports 9; according to the invention, the left binding clip 7, the right binding clip 8 and the clamping block 4 are all in a cuboid structure, when the clamping block 4 is hinged with the left binding clip 7 and the right binding clip 8, taking the attached drawing 4 as an example, the two clamping blocks 4 above the attached drawing 4 are hinged with the corresponding positions on the inner sides of the left binding clip 7 or the right binding clip 8 at the lower outer corners of the clamping block 4, so that the clamping block 4 can rotate conveniently, the outer side surface of the clamping block 4 is provided with an arc-shaped support frame 10, the left binding clip 7 or the right binding clip 8 corresponding to the arc-shaped support frame 10 is provided with a support telescopic groove 11, the support telescopic groove 11 is arranged on the inner end parts of the left binding clip 7 and the right binding clip 8, and the bottom end of the arc-shaped support frame 10 is inserted into the corresponding support telescopic groove 11. Two support expansion slots 11 that correspond on the double-jaw can set up to link up from top to bottom, if tip is longer in left binding clip 7 and the right binding clip 8, it is longer that the position distance of arc-shaped clamping mouth 9 to double-jaw bottom is longer, two support expansion slots 11 that correspond can stagger the setting, arc support frame 10 also staggers the setting like this, two arc support frames 10 just can not roof pressure each other, prevent the slippage, two arc support frames 10 in figure 2 are just dislocation set, two clamp tight piece 4 can open by the wide-angle like this.

The invention relates to a pair of clamping pliers for installing a cross buckle for connecting a protective net on a building, which is basically the same as a common pliers in structure, keeps the use habit of the pliers with the original structure, is easier to popularize and accept, is simpler in structure, only adds a set of clamping blocks 4 capable of being linked with a pliers handle on the structure of the existing double-headed pliers, the four clamping blocks 4 are equivalent to a set of double-headed pliers structure, the mutual clamping of the four clamping blocks 4 and the double-headed pliers adopt the same pair of pliers handles 1, the efficiency of installing and connecting the cross buckle 14 is doubled compared with that of the double-headed pliers, and the pair of clamping pliers is simple in structure, low in cost and capable of keeping the use habit the same as that of the existing pliers.

An opening spring 12 is arranged between the two forceps handles 1. The expanding spring 12 can keep the two clamp handles 1 expanded, and is convenient to operate and use.

And a tension spring 12 is arranged between the arc-shaped support frame 10 and the corresponding left tong head 7 or right tong head 8. When the jaws of the double-ended pliers are opened, the arc-shaped support frame 10 is pulled to retract into the support telescopic groove 11 under the action of the tension spring 13, the clamping blocks 4 rotate outwards around the connecting rotating shaft, and therefore the two corresponding clamping blocks 4 are opened.

When the jaws of the double-head pliers are closed and clamped, the bottom ends of the arc-shaped support frames 10 extend out of the support telescopic grooves 11 under the jacking pressure of the clamping surfaces of the jaws, and the arc-shaped support frames 10 extend out and are jacked on the corresponding clamping blocks 4, so that the two corresponding clamping blocks 4 are clamped.

As shown in fig. 1-4, the clamping pliers for installing the cross buckle for connecting the protective screening on the building can be used conveniently like common pliers, and by taking fig. 2 as an example, the two pliers handles 1 can be used for clamping and installing the cross buckle 14 by horizontally clamping, the two pliers handles 1 are horizontally held, as shown in fig. 4, the upper jaw of the double pliers head is aligned with the upper end of the cross buckle 14, the lower jaw of the double pliers head is aligned with the lower end of the cross buckle 14, the left two clamping blocks 4 are aligned with the left end of the cross buckle 14, the right two clamping blocks 4 are aligned with the right end of the cross buckle 14, and then the two pliers handles 1 are directly clamped, i.e. the cross buckle 14 is clamped and installed on the steel wire rope 15 at one time.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
